IMPLEMENTATION AND THE PARAMETER OPTIMIZATION OF THE AUTOMATIC SYSTEMS OF CONTROL BY LUMINANCE APPARATUSES IN UNIVERSITIES

Abstract

Control systems LED illumination are in higher grade promising apparatuses real and future. Owing to the behaviors of emitting diodes, by such systems possibly actualize of entire inspection over luminance apparatuses in the decision of the objectives of illumination in frequent :

-Obtaining of highly steady  the performance of the ray of emitting diodes ;

- The controlled changeover of luminous flux ;

- The high EFFICIENCY of system ;

- The inspection of the illumination of acting surfaces ;

- Inspection and controls by the demand of electricity ;

- Inspection and controls by colored temperature.

The forecasts of evolution and the basic directions of LED illumination till 2020 г. [1] made in 2009 year showed on current derived average the correctness. The exponent approximate calculation of saving from the application of effective illuminants and the systems of their feed and controls.

The pair potential of saving of electricity in luminance apparatuses maybe achieve :

- By expansion the productions of effective illuminants and the areas of their application - minimum 14 %;

- By the gain of the luminosity factor of illuminants - 6 %;

- By the boost of the stability of the behaviors of illuminants - 3 %;

- By boost the efficiency of luminance devices - 6 %;

- By the improvement of operating behaviors of luminance devices - 3.5 %;

- By the decline of power luminance devices, in particular owing to the utilization of electron start-controlling stiffener (EPRA) - 1.5 - 2%.

By improving of the means of illumination too can be achieved electricity saving :

by the expansion of the range of application of the system of general local  illumination - 6.5 %;

· in the application of the systems of the regulation of general illumination depending on the level of natural illumination - 4.5 - 7.5 %;

· by the expansion of the application of the system of combine illumination - 4%.

Total possible saving compiles 45 - 50% from the size of electricity which today is spent on illumination [1].

What  else possibly decline of the demand of electricity, and due to what?

Are  determined basic performance affecting the power of LED illuminants and the meanses  of their implementation in control systems. As a result of operation are determined and optimized the most basilar performance of the systems of the illumination of the rooms of universities for use in the automatic systems of LED illumination in development and infusion. Are determined the time intervals of lead-out on required power in inclusion and the turned-off of luminance apparatuses. The analysis of the application of these performance in control systems showed the additional saving of consumed electricity on 10-30%.
